To reach a M is no small feat when you start with a couple of k's. It takes courage, patience, a clear vision of the future and then act accordingly.
It took five years with five k's to be this close to a M. While half a M is not the milestone, it is worth noting. Halfway there now, with just a little more push.
As a disclosure, the letters k and M as mentioned in this post are not related to a specific data format. View how you best see fit.
